Feel free to use and include in your own published GRUB Themes, but please give credit if you do!

Create a folder inside your GRUB theme's directory, can be named anything.

Place in folder alongside numbered images in .png format. Images must be zero padded (01, 02, 03, 04...). Up to 99 images are supported.

Ensure the script is executable with chmod +x ./Cycler.sh

Ensure you have full permissions over your theme folder, use chown to set yourself as owner if not.

Set the script to always run on startup with crontab -e and add @reboot **PATH TO Cycler.sh SCRIPT** to the bottom of the list. This can be changed to any length of time that you desire.
